To all our readers -- we now offer (as desceribed in CMP4) 2 versions of our world-famous EBM **plus** a simple to use spreadsheet version of Thomas Stocker's 2013 Science paper on climate change mitigation.

I updated the spreadsheet version of the EBM so that it works properly. The sheet has been around on various web pages for many years, but on closer examination, I find these versions don't work the way they should. The new revised version is available on the downloads page. Older versions you find around the web are incorrect (unless they've been modified by others).
